On Thursday 19th September Andriza Liebenberg spoke about "Tunneling on the Western Front in WWI".
Many of our members will know of the enormous explosions, especially those near Messines Ridge on the Western Front, which were part of the actions during WWI. Andriza told of offers made early in the conflict to use a technique called clay kicking which was widely used to construct mine and sewer tunnels in the south of England. The British Army was not interested - until it was literally shaken by the German use of tunnels under their trenches and positions. Since much of the western front was underlain by the same clay material which was encountered in the mines in Cornwall, permission to engage kickers and their fellow miners was granted and Allied underground operations began.
Our speaker told of some of the listening attempts, both with and without sophisticated equipment, which both sides undertook to try and locate the enemy's tunneling and counter-mining noises in order to breach the tunnels before they were used.
Extremely large quantities (hundreds of tonnes) of ammonal (packed in special rubber wrapping) and/or gun-cotton were used, each of the sites causing anxiety to nearby (or above!) troops waiting for detonation day... in one case the explosives were placed a year before their detonation. Even if the explosions missed specific troop concentrations, the effects on morale were very debilitating.
Andriza described many of the tunnel layouts and showed slides of the craters when these were the results on the surface.
As with many administrative records, the locations of the placed explosives was not always remembered. In 1955 lightning struck an electricity pylon which had been erected unbeknown atop one of these 'mines". Fortunately the only victim seems to have been a cow.
Andriza's lecture has been added to the Video Library.

Time to join the Zoominars
For those members still anxious about Zoom lectures, please give them a try! Go onto the internet and open your web browser at www.zoom.us . If using a cellphone visit the app store. Once you have the app on your device - computer or cellphone - choose to join a meeting. Either use the link which is provided in the invitation or type in the meeting code and then the password,also from the invitation, as requested. There are usually two Zoom sessions per evening.
You do NOT need to have a camera - unless you are the speaker or a chairman - although it is always interesting to match faces to voices. As in the auditorium, you do not HAVE to ask the speaker any questions, but there are ways in which you can draw the chair's attention so you can do so.
